These instructions have been tested on Ubuntu 17.10, but they should be easily adaptable to other flavours.
The checkpoint VPN software currently only works with firefox-esr, due to most browsers dropping support for the java plugin. After much experimentation, I eventually got it to work, here’s how :
- Add oracle java 8 & mozilla apt repositories
# sudo apt-get-repository -y ppa:webupd8team/java
# sudo add-apt-repository ppa:mozillateam/ppa
# sudo apt-get update
- Install the required packages.
# sudo apt-get install firefox-esr oracle-java8-installer libstdc++5:i386 libpam0g:i386 libx11-6:i386 xterm
- Install the java plugin for firefox
# mkdir ~/.mozilla/plugins
# ln -s /usr/lib/jvm/java-
- Java security settings need to be modified to enable the checkpoint java plugin to work correctly.
# sudo vi /usr/lib/jvm/java-8-oracle/jre/lib/security/java.security
Change the below line –jdk.jar.disabledAlgorithms=MD2, MD5, RSA keySize < 1024
tojdk.jar.disabledAlgorithms=MD2, RSA keySize < 1024
- Remove the standard version of firefox
# sudo dpkg -r firefox
- The first time you run the plugin, firefox must be running as root, to install the neccessary plugins.
# sudo firefox-esr
If firefox complains about not being able to connect to X11, run “xhost +” first, and try again.
- Browse to your vpn login page, login, connect to vpn, accept all java confirmations and click yes when prompted to install the checkpoint plugin.
- Exit firefox, and run under your own account.
